About Light Days
A light day (ld) is the distance light travels in one day through a vacuum, equal to approximately 25.9 billion kilometers. This unit bridges the gap between planetary distances and interstellar space. The Voyager 1 spacecraft, humanity's most distant object, is currently over 0.9 light days from Earth. The outer edge of our solar system (heliopause) is roughly 0.6-0.7 light days away. The Oort Cloud, a theoretical sphere of icy objects surrounding our solar system, extends from about 0.16 light days to possibly 1.6 light years.
About Feet
A foot (ft) is equal to 12 inches or 30.48 centimeters, originally based on the length of a human foot. It remains widely used in the United States and some other countries for measuring height, room dimensions, and distances. For reference, a standard door is about 6.5-7 feet tall, ceiling height in homes is typically 8-9 feet, and a basketball hoop stands 10 feet high. The foot is also used in aviation (altitude) and real estate (square footage).
